To all ywhom t mayV concern:

Be .it known that I, KEEMIT Hoses, a cit-i- Zen of the United States, residing at San Antonio,` in the county of Bexar and State of Texas, have invented new and useful Improvements in Gasoline Filters, of which the following is a specification.

This invention relates to new and useful improvements in filters and more particularly to a filter whiclnis especially adapted :for use on gasoline storage tanks of motor vehicles. The main object of my invention is the provision of a filter of the above type which is carried by an attaching sleeve which may be secured to the usual flange of'the filling opening in a gasoline supply tank and whereby the usual closure cap may be attached tothe sleeve in the usual manner `Another object of` my invention is the provision of a filter for gasoline which will separate the `dirt and water from the gaso-v line before the gasoline is passed into the usual storagetank and includes novel means for supporting the filter within the tank.

With the above and other objects in View, my'invention consists in the novel features of construction and the combination and arrangement of parts to be hereinafter more fully described, pointed out in the claims and shown in the accompanyingdrawings, in which:

Fig.` 1 is a sideelevation of my improvedk filter showing the supporting` means in section,

Fig. 2 is a top plan view withthe closure cap removed, i

Fig. 3 is a longitudinal section on the lines 33 4of Figure 1, Y

Fig. 4 is a detailed transverse section on the lines H of Figure l, and

Fig. 5 is a detailed section on the lines 5-5 of Fig. 2. j l

Referring more particularly to the drawings, the 'numeral 1 indicates a fragment of a gasoline storage tank having a filling opening 2 which is surrounded by an upstanding flange 3; This is an ordinary construction of a gasoline supply tank which is used on motor vehicles and upon which the usual closure cap 4 is mounted'for normally closing the filling opening.

My improved filter comprises an attach- ,ing sleeve 5, having an internally threaded portion 6 which is adapted to be mounted upon the threaded flange 3 and has an inwardly projecting portion t which rests upon the upperfend, of the ysleeve 3 and projects inwardly beyond the wall of the opening 2 torniing'the shoulder Extending upwardly from the shoulder 8 is the threaded flange 9 upon which the usual closure cap 4 is mounted. y,

My improved filter comprises a body `10 having openings 11 extending longitudinally of the body and is provided with additional openings 12 at the bottom of the body. These openings 11 and 12 extend circumferentially of the body and are closed by fine mesh `'screen wire 13, this screen wire is of. a suitable meshto exclude the passage therethru of water and small particles but will readily permit the gasoline to pass thru the same into the tank.

' .The body has a circumferentially bracing portion ltdisposed between the two sides of openings 11 and 12 and in order to provide substantially bracing means for the body, rods 15 are arranged within thebody asshown in rFigures 3 and 4, preferably arranged in pairs opposite the screen portions 13 and spaced therefrom asshown in Figure 3. The upper ends of the rodsy are riveted to the wall of the body 10 above theopenings 11 while the lower ends of the rods are riveted to the circumferential portion 14. These rods will not only form the brace for the body to provide a substantiallyv rigid structure but will prevent the usual filling nozzle from coming into contact with thescreen wire when filling the tank.

-.'I`l1e upper endv of the body is pro-vided with an annular flange 16 whichis adapted to rest upon the shoulder 8 andl has diametrica-lly opposed notches 17 therein and pivotally connected tothe flange 16 at the opposite sides of the body are the resilient locking members 1S. These locking members are pivotal-.ly connected to the flange 16 at opposite sides as shown at 19 so ythat the free ends of the locking members may be swung inwardly over the upper end oi' the body of the iilter. forl disengaging the recessed portions 20 of the locking members from the inwardly projecting members 21 upon the inner 4wall ot the flange 9.

It will be noted that the locking members y 18 are each provided with a central indentation forming the'recessed portions 20 and upon opposite sides of the recessedportions.

the locking members are raised, thus in placing the filter in position within the sleeve 3,

5 locking members 18 until they are positioned between the recessed portions 2O thus retaining the filter body in position as illustrated in Figure 1. Then it is desired to remove the filter body t-he free ends of the l locking members are moved inwardly over the upper end of the body so as to disengage the lugs 21 from the `rrecessed portions 20 and by turning the filter body until the notches 1? align with the lugs T21, the filtei may be quickly and readily removed.

Upon opposite sides of .the filter bod-y, adjacent the upper end thereof, tongues 9.2 are struck inwardly so as to not only provide an air ven-t within Athe tank being filled, but

to provide a finger piece fupon ythe interior of the body to facilit-ate its removal.

It will be apparent freni the foregoing that my improved device may be 'quickly and readily applied to gasoline'storage tanks 25 of motor vehicles, by removing the usual closure cap 4 and placing `the sleeve v5 in `position upon the usual threaded flange surrounding the opening. It will be apparent that a slight change may be made in the above .for applying the device .to storage tanks wherein the opening is normally closet by means of the plug instead of a cap illustrated in the drawings and described above.

W'hile I have shown and described the preferred formof my invention, it will be obvious that various changes in the details of construction and inthe proportions may be resorted to for successfully carrying my invention into practice without sacrificing i0 any ofthe novel features or departing from the .scope of the appended claims.

Having thus described my invention, what l c-laim is:

1. ln combination with the sleeve having an inwardly extending shoulder and oppositely disposed lugs upon the interior of .the sie fe and above the shoulder, a filter having an angular flange at its upper end resting upon said shoulder, said flange having notches at diametrically `opposite poi-nts to permit the passing therethru of said lugs, pivoted locking members carried by the flange and normally resting thereon, recessed portions intermediate the ends of said locking members for receiving therein said lugs, to retain the fiange against movement relative to the shoulder.

2. ln combination with a sleeve, an inwardly projecting angular shoulder on said sleeve, oppositely disposed lugs upon the interior of said sleeve above the shoulder, a filter body, a flange at the upper end of the body, notches in said flange at diametrically opposite points to permitthe passage there# through of said lugs, locking members pivotally connected at opposite points to the flange, said locking members having recessed portions intermediate their ends with raised portions upon oppositesides of the recessed portions, whereby upon turning movement of the filter after the lugs have passed through the notches said lugs will ride over the `raised portions into the recessed portions. V

S. In con'rbination a sleeve, an 'inwardly projecting angular shoulder on said4 sleeve, oppositely disposed lugs upon the yinterior of said sleeve above the shoulder, a 4filter body, a flange at the upper end of .the body,- notches in said flange in diametricalljv opposite points to permit the-passage therethrough of sai-d lugs, locking members pivotallyconnected at opposite points to the flange, said locking members having recessed portions intermediate their ends with raised portions upon opposite sides of the' recessed portions, whereby upon turning movement of the filter after the lugs have passed through the notches, said lugs will ride over the yraised portions into lthe recessed portions, said locking members having their free ends moving inwardly over the upper' end of the filter whereby to remove said lugs from the recessed portions.

In testimony whereof affix my signature.
